A 39 MB version of Puppy 1.0.3 for slow connections that uses the dillo browser (no Firefox, Opera or Mozilla) and notably does not include Abiword (if required these programs are added with pupget). Also, the last release of BareBones 1.xx series is Puppy is version 1.0.4

pUPnGO is a basic building block - extract of the very "core" of Puppy Linux. It is 6Mb without GUI 8Mb with.

Gently modified org. initrd (changed BB and ntfsg3), mainssfs is CLI only and contains only static build programs.
This gives a basis to continue building all static or using any libc you want (ulibc, libc old or new etc.- any version) even loaded as a sfs after creating a save file or load it with otf-sfs-loader. So you can install/uninstall libc without breaking the core system. Busybox resides in initrd.gz and are copied at boot if not present... pUPnGO - thread
